There are some interesting products on the market today. The one that catches my attention was this company www.vocera.com. They provide a communication system for enterprise like applications such as offices and hospital. It combines wireless, voip, voice recognition and text messaging.
It would be nice to transform this type of technology into more wide area usage such as with Cell phones etc.
The concept to investigate is how to make the person a part of the network, this meanings you can reach them by any available means at any time. This means some degree of translation from different medias.
This is a very good area to explore in light of broadband connectivity.
